(string,array) (可选) List of terms. Can be an array or a comma separated string. If you want to enter terms of a hierarchical taxonomy like categories, then use IDs. If you want to add non-hierarchical terms like tags, then use names.

For non-hierarchical terms (such as tags), you can pass either the term name or id. If you pass the id there is only one caveat: You must pass it as an integer, and it must be in an array. This is necessary because any non-array value passed will be converted to a string, which will be interpreted as a term name.
